To all whom t may concern:

Be it known that I, LOUIS LAvERGNE DIT RENAUD, of the city of Montreal,in the Province of Quebec and Dominion of Canada, have invented certainnew and useful Improvements in Gullies, of which the following is afull, clear, and exact description.

This invention relates to improvements in gullies for delivering streetdrainage into sewers, and the main object is to provide a simple andinexpensive gully which may be 'very easily cleaned and which willabsolutely prevent. the escape of foul odors from the sewer.

A further object is to provide a frost proof gully which will preventthe freezing of water in the lower part of same and will also not beheaved by frost in the ground.

A still further object is to provide means for quickly and easilyadjusting a gully to its location when installing same.

Another object is to provide a gully which will absolutely prevent theintroduction of large objects into the sewer which would tend to clogthe same.

To accomplish these objects, I provide a top section having a removablecover extending to and forming the road edge of the top. The top sectionis mounted on a table superimposed on a cage section and carrying withinthe section a straining cage. The cage section is supported on a pipeconnect ing with the sewer by means of a tapering valve sectioncontaining a delicately balanced valve. 1n the bottom of the connectingpipe is a large mesh basket. A special cover is provided which issubstituted for the grate in cold weather.

In the drawings which illustrate my invention z-Figure 1 is a verticalsectional view on the line 9-10 of Fig. 2. Fig. 2 is a front viewshowing on the right a half front elevation and on the left a section onthe line 78 of Fig. 1. Fig. 3 is aplan view of the top of the gully.Fig. 4 is a det-ail sectional view of the valve. Fig. 5 is a plan viewof the winter cover. Fig. 6 is a sectional view of same on the line11-12 of Fig. 5. 1

In the above defined figures, 13 designates the top section of the gullywhich is substantially square, as shown in plan, Fig. 3, and is providedwith a cover 14 resting on fianges 15 formed on the section. The coveris provided with a pair of lugs 16 to prevent the same being readilydisplaced, and with a cleaning the gully. The outer o-r road side of thetop section is open, the ends 18 of the section being provided withvertical grooves 19 which receive the ends of the grille 20. The topsection rests on a table 21, which is provided with a peripheralretaining flange 22, except at the front, as seen in Fig. 2, to allowdrainage to readily enter the gully. The table 21 is provided wit-h arectangular aperture 23 through which depends a straining cage 24supported by a iange 25 engaging the flange 26 of the table. This cage24 is in the form of a substantially rectangular box having the front 27and ends 28 solid, and the back and bott-om formed ot' a grating 29 ofsuitably line mesh. The cage is inclosed within a slightly taperingsection 30, which supports the table 21, the table being alined on thesection 30 by means of the flanges 26, as seen in Figs. 1 and 2. Thevalve section 31, which supports the cage section 30, is in the form ofan inverted t'rustum of a pyramid and is provided at the top with ashoulder 32 on which the cage section stands, and a retaining flange forthe said section. The opposite end of the valve section is provided witha long depending neck 34 adapted to occupy the long throat 35 of thegully pipe 36. The gully pipe 3G extends downwardly a suitable distanceand is provided at the bottom with a discharge pipe 37, opening from theouter or street side of the gully which connects with the sewer. Thispipe 37 is circular, while the gully pipe 3Gis preferably square orrectangular. The bottom of the pipe 36 is provided with a base plate 38of suitable dimensions, cast integral therewith, in order that the gullymay stand firmly on its foundation when installed. l

1n the angle between. the pipes 36 and 37', I provide a basket 39 oflarge mesh which will hold any large objects, such as tin cans, etc.,which may be introduced into the gully by lift-ing the cage 24. Byremoving the cover plate 14, lifting out the cage 24 and opening thevalve, the basket 39 may be readily drawn up by means of a suitablehook, and any foreign matter therein removed. The valve comprises aplate 40 sloping downwardly from the periphery, where it rests on thesloping walls of the valve section 31, to a central rectangular aperture41 surrounded by a depending flange 42. The two leaves 43 of the valveare hinged on pins 44 and open downwardly. These leaves are hinged ateach side of the plate to the ange 42 and extend toward the center. Theouter end of the leaf of the valve is formed into a. counterbalance 45which may be loaded if necessary to maintain the valve leaves normallyclosed, as shown, in Fig. 4. These valve leaves are preferably made ofaluminum, or other light metal, in order that they may move easily. Thecounterbalances 46 are arranged to just close the valve and no more, inorder that a very small amount of water or current of air entering thegully will open the valve and pass to the sewer. In this way any rush ofwater through the sewer will draw in fresh air through the valve toventilate the sewer but as soon as the suction stops, the valve closesto prevent the rise of foul odors from the sewer. It will be readilyseen from the drawings that the hinges of the valve leaves and thecounter balances are protected from the inrush of water into the gullyand are, therefore, equally protected from becoming clogged with gritand refuse carried by the water.

In many cities the laws rela-ting to eX- pectorating on the sidewalk orstreet are very strict and are rigidly enforced, some cities going sofar as to provide special receptacles at intervals along the streets. Toovercome this expense and also to do away with the necessity of tendingthese cuspidors, I provide a cuspidor in the cover plate of the gullywhich will be both convenient and sanitary. This cuspidor consists of asmall semicircular grating 47, provided with a pivoted semicircularcover 48 sunk into the plate 14 so as to be flush with the surfacethereof. The bars forming this grating are triangular in cross sectionand are located with the apex uppermost, as shown in Fig. 1, in orderthat there may be no top surface for anything to adhere to and bedistributed over the sidewalk by the feet of passing pedestrians. Itwill be clearlyy seen in Fig. 1, that all droppings from the gratingfall directly on to the valve from which they will be washed into thesewer by the first infiow of water.

It hasbeen amply demonstrated that dry ground is much lesspenetrated byfrost than wet ground, and also that'dry ground does not exert the sameheaving effect on buried or partially buried objects when frozen, as wetground. It will be noted in the drawings that the joints between thesec-V tions of the gully at the flanges 33 and 35 are very open. Nocement or other filling is used in these joints when erecting the gullyinorder that the open joints may pro vide a means for draining theground 1mmediately surrounding the gully. This draining insures dryground, not greatly elfected by frost, with the result that the gully isnot heaved up in cold weather.

To protect the gully in cold weather and prevent the case becomingfilled with ice or snow so as to be useless in case of a sudden thaw, Iprovide a special winter cover plate 49 adapted to completely iill theapert-ure 23 in the table 2l. This plate 49 is provided with a flange 50which lies on the flange 26 of the table and holds the plate in place. fAn aperture 51 is formed in the plate along the outer edge thereof andprovided with a sliding cover 52. When cold weather sets in, the cage 24is pulled up and stored in the top section, as shown in dotted lines inFig. 1, and the winter cover plate. 49 placed over the opening 23. Thecover 48 of the cuspidor is also closed. rIliis prevents thc entrance ofcold air into the gully and sewer and prevents the possibility offreezing same. In case of a sudden thaw, the cover 48 is opened to drainthe side walk and the cover 52 of the plate 49 shoved back to open theaperture 51 for street drainage. I

Instead of the winter cover plate being designed to cover the aperture23 in the table 21, I may provide a cover plate adapted to fit in frontof the grate 20 to prevent snow and cold air from entering the gully,

or in some cases a cover plate may be provided both in front of thegrating and to delicately balanced than usual to allow the ventilationof the sewer. rlhe valve is also more readily accessible. As it isalmost impossible to have the sewer a uniform dis tance below the streetlevel, each gully requires considerable tting when installed. Toovercome this, I provide the longv neck of the valve section fit-tinginto the long throat of the pipe, so that the gully may beeasilyadjusted to the street and sewer levels.

Various other advantages will be apparent to those skilled in thescience of drainage. ForV inst-ance, it is well known that currents ofair within the sewer do not flow in the same direction at all times butare controlled more or less by the iiow of sewage. When the flow of thevair current is away from the gully, the draft will be quite sufficientto open the delicately balanced valves of my device to thereby. permitcurrents of fresh air to enter the gully and ventilate the sewer.- Onthe other hand, a sudden back pressure of air toward the gully, due toany cause whatever, willbe tightly sealed within the lower Section otthe gully below the valve and prevented from escaping to contaminate theair of the street.. This method of ventilation is one of the importantresults attained in the present invention and Cannot be attained by anyother gully construction of which l am aware.

Having thus described my invention, what l claim is:-

l. A gully comprising a top section having a removable top and openfront, a grating for Said open front, an intermediate section, a tablesupport-ing the top section above the intermediate Section, a strainingcage supported by said table Within the intermediate section, a valvesection below said intermediate section, a one-way valve in Said valveSection, a pipe connecting said valve section to the sewer, and a basketadj aeent the bottom of said pipe.

2. A gully comprising `a top Section having a continuously open frontand top, a grating for the front, a removable cover for the top, anintermediate section below said top Section, an apertured tablesupporting the top section on the intermediate section, a cage suspendedthrough the table aperture and occupying the intermediate section, aninverted frusto-pyramidal valve Section supporting the intermediatesection, a downwardly opening valve removably mounted in said section,means for maintaining said valve normally closed, a pipe connecting saidvalve section to the sewer, a large meshed basket adjacent the bottom ofsaid pipe, and an integral foundation plate at the bottom of the pipe.
